# Starter Shoulder Extension Upgrade EN

The Cross-Starter allows you to enhance your Pro/Mag-Starter and increase your comfort while playing, and improve your in-game aim even more precisely than the classic Starter CQB.

For video setup, [you can check our YouTube tutorial Playlists](https://www.youtube.com/channel/UCnrBJ8KQE3-JQrwVBib7J-w).

Make sure you work in a clear area and be very careful, some parts can be easily lost.
